Ryan Shucard, the Capitol Hill aide who allegedly tried to bring a 9 mm handgun and magazine to work Friday, was released from police custody on Saturday afternoon after pleading not guilty to a felony charge for carrying a pistol.

Shucard exercised his Fifth Amendment right during his minute-long arraignment, standing silently beside his lawyer in khaki pants and a long-sleeved, collared shirt with shackles around his ankles and wrists. With no objection from the government lawyers working on the case, D.C. Superior Court Judge Gerald Fisher released Shucard with instructions to return to court on Aug. 7.

When the Colorado native entered the courtroom around 1:30 p.m., a blond woman began dabbing her eyes with a tissue. She was sitting next to a girl and man who later identified themselves as members of Shucard's family. The trio followed Shucard out of the courtroom. Shucard, his family and his lawyer, Jason Kalafat, declined to comment to CQ Roll Call.

Shucard has been placed on unpaid leave from the office of Rep. Tom Marino, R-Pa., where he had been serving as press secretary since May 2014. The University of Northern Colorado and George Washington University alumnus got his start on the Hill in October 2011 as a staff assistant for then-Sen. Joseph I. Lieberman, I-Conn.

What might have provoked the incident, which resulted in Capitol Police arrested Shucard around 9:15 a.m. on Friday morning, remains unclear, but the confiscated handgun has been raising new questions about campus security.
